Parameters

q  Complex32
The Q matrix obtained by calling QRFactor(Complex32, Int32, Int32, Complex32, Complex32).
r  Complex32
The R matrix obtained by calling QRFactor(Complex32, Int32, Int32, Complex32, Complex32).
rowsA  Int32
The number of rows in the A matrix.
columnsA  Int32
The number of columns in the A matrix.
tau  Complex32
Contains additional information on Q. Only used for the native solver and can be null for the managed provider.
b  Complex32
The B matrix.
columnsB  Int32
